Internal consistency, alternate form, and stability coefficients for the CAK‐C were obtained for a sample of 135 educable mentally retarded children. The internal consistency and alternate form coefficients appear to be acceptably high, and the stability coefficients, while appreciably lower, still suggest some degree of consistency over a year's time. The reliability of the CAK‐C is judged to be satisfactory for EMR children.
